摘要:
A component power cable having a pair of elongate conductive members each connected at a first end to a power distribution unit connector and at a second end to a component power supply connector, wherein the cable has sufficient resilience to impart a generally collapsed configuration to the component power cable, with the first end generally proximal to the second end. The component power cable is extendable from the collapsed configuration to an extended configuration by displacement of the first end to a position distal to the second end, wherein energy stored in the resilient cable by such displacement restores the component power cable to the collapsed configuration upon return of the first end to a position proximal the second end. The resilience may be provided by a spring element or by an elastomeric sheath.

A method of printing on a sheet of paper comprises drawing a first sheet of paper from a first paper source into a printer having an optical scanner and a print head, scanning a first face of the first sheet to determine the presence or absence of print thereon. In response to detecting print on the first face, the print head is caused to print an obstruction on the first face. In response to detecting no print on the first face, the print head is caused to print new matter on the first face. The method enables a printer to accept used paper while eliminating confusion over which face contains the new matter.
摘要:
A computer storage rack has vertically arranged bays for receiving electrical power-consuming components, an elongate electrical power distribution unit (PDU) having power distribution sockets vertically spaced along the length of the PDU, and a hinge pivotally coupling the PDU to the rack along a vertical axis. The PDU pivots about the hinge between a position proximal to the bays and a position distal to the bays. The apparatus further comprises a component power supply cables that are resiliently extendable from a collapsed configuration to an extended configuration. Each of the component power supply cables is connected between one of the power distribution sockets and an adjacent one of the electrical power-consuming components, and each is resiliently extendable in response to pivoting the PDU to the distal position and resiliently collapsed in response to pivoting the PDU to the proximal position.

The instant disclosure teaches transposons and methods of the instant invention for making Protein Fusions by rapid, random shuffling of protein domains to produce novel protein fusions. This system is generally applicable to production of multifunctional chimeric proteins in vivo and in vitro. The methods and constructs of the instant invention can be used to randomly create both carboxy- and amino-terminal protein fusions in vivo. The methods and contructs of the instant invention are useful in the development of a protein domain library, in the construction of multifunctional enzymes, and in the accelerated evolution of new enzymatic activities.

A computer system includes a rack-mountable server unit with a closed server housing. The server housing has a channel with a recessed channel wall in conductive thermal communication with a processor or other heat-generating component. An elongate conduit is received into the channel of the server housing in conductive thermal communication with an external surface of the server housing. The server is cooled by conductive fluid flow through the conduit, with no appreciable airflow through the server housing. The system may be operated in an optional burst cooling mode, wherein a volume of cooling fluid is trapped in the conduit for a period of time before being quickly released.

A networking system includes a host adapter card including a card connector having four transceiver pairs and a mechanical connector configuration, and a controller having control logic for detecting whether a single-channel connection or a four-channel connection is made to the card connector. The controller further includes control logic for communicating over a network using a default, four-channel-protocol in response to detecting the four-channel connection or using an alternative, single-channel-protocol in response to detecting the single-channel connection. The system further includes an alternative-network compatibility device including a first connector configured for releasably mating with the card connector and a second connector having a different mechanical connector configuration than the card connector. The alternative-network compatibility device includes a transceiver lane from the first connector end to the second connector end, which transceiver lane is placed in connection with one of the four transceiver pairs when mated with the card connector.
